Ship for making upwelling in lake

Abstract

The invention relates to the technical field related to water area treatment, in particular to a ship for making upwelling in a lake, the ship for making upwelling comprises a ship body support, a buoy, a water impeller rotating mechanism and a pressure-resistant bin assembly, flowing of a water body is accelerated through the effect of propeller blades so as to simulate the process of natural upwelling, and therefore lake water upwelling from the lake bottom to the lake surface is formed, and the upwelling effect is achieved. Water layering of a lake can be effectively broken through, nutritive salt of a lower-layer water body is conveyed to an upper-layer water body and then absorbed by algae in the upper-layer water body through photosynthesis, meanwhile, downflow caused by upflow can convey sufficient dissolved oxygen in the upper-layer water body to the anoxic lower-layer water body, the activity of microorganisms in the lower-layer water body is enhanced, and the oxygen-rich effect is achieved. And the increase of the dissolved oxygen in the bottom layer water body can also play a role in inhibiting the release of nutritive salts in the bottom mud, so that the effect of improving the lake water quality condition is finally achieved, and the lake eutrophication problem is solved.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to a boat for manufacturing upwelling in lakes. Background technique [0002] Natural upwelling is an oceanographic phenomenon that refers to the sea current rising in a straight line from below the surface of the sea, which can lift the nutrient-rich deep seawater to the true photosphere, providing sufficient nutrients for the growth of surface phytoplankton, thereby improving the ocean's primary productivity; [0003] The problem of eutrophication in lakes mainly occurs in areas with slow water flow, where the self-purification capacity of the water body is weak, and the water in high temperature seasons such as summer will be stratified. The stratification of the water is the main reason for the weak self-purification ability of the water body, and also the main source of the deterioration of the lake water quality. Therefore, the present invention proposes an upwelling ...

Problems solved by technology

[0003] The problem of eutrophication in lakes mainly occurs in areas with slow water flow. In these areas, the self-purification ability of water bodies is weak. In summer and other high temperature seasons, the water body will be stratified. The upper water body has high temperature and low density, and the lower water body has The stratification of the water body is the main reason for the weak self-purification ability of the water body, and it is also the main source of the lake's water quality deterioration. For this reason, the present invention proposes a boat that produces upwelling in the lake to solve the above problems
